Specification of Letters Patent. I

Application filed December 3, 1917, Serial No. 205,013. Renewed January11, 1921. Serial No. 436,613.

To all whom it may concern: 1

Be it known that I, JOHN J. CHAPIN, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Rolling I This invention relates to screens of the classwhich are permanently fitted to win dow frames or other openings ofbuildings, and having a flexible screen adapted to be rolled within acasing or housing provided preferably at the top of the window.

The invention has for its principal object to provide a rolling windowscreen having side guides for the unrolled screen andclamps thereforconcealed within the guides, thereby, assuring a pleasing finish to thewhole screen structure and avoiding unsightly accumulations of dust uponor within the screen fittings or mountlngs.

A further object is to provide a simple, and-practical rolling screenwhich may be inexpensively made and applied and 1s efiicient and durablein use, and which clamps the screen edges easily and securely withoutinterferi with the free opening o-r closing orconvenient cleaning-of theWlIldow sashes. To these and other ends the invention consists incertain improvements and combinations of parts all as will behereinafter more fully descrlbed, the novel features being pointed outin .theclaims at the end of the specification.

Patented Aug. 16, 1921.

Fig. 9 is a detail rear sectional perspective view of the lower clampbearing block in the right hand screen guide.

a Similar reference characters in the several figures indicate the sameparts.

The numeral 1 indicates the flexible screen, preferably made of wirenetting, secured at one end to a Spring roller 2, which is journaled atits ends in brackets 3, located above anopenin'g 4, such as a windowbounded by strip 9 which looks this end of the screen within a dovetailshaped slot 10 formed in the inner wall of a hollow transverse screenbottom rail 11. The latter is preferably molded or rolled from sheetmetal, and at its ends is closed by blocks 12, 12, shown in Figs. 1, 4and 7. These blocks are slotted vertically at their outer edges whichare guided "upon the laterally projecting inner flange portions. 14 ofhollow metal guides at the sides of the window frame 5, which alsocomprise the inner wall 15 and a connecting wall 16. Each of the guidesis securedat its ends, by screws 17, tothe face of the outer sash stop,or rail 18 of the window casing so that the guide flanges 14;, extendlaterally inwardly toward each other. tion the guides hold the Screenclose to the window sash and do not interfere with the closing of theshutters or blinds which may be. fitted within the casing 5. There maybe one or more intermediate screw fastenings 19 for each guide,depending upon its length, as Shown in Figs. 1 and 2. These screws1 9are set into the frame portion 18 before the guide is applied thereto,the screw heads standing off from the frame sufiiciently to snuglyreceive beneath them the narrow base wall 16 of'the guide which istransversely slotted at 20 to receive the body or stem of the scre'w,thehead of which passes laterally through a curved slot 21 made in theinner side wall 15 of the guide. The communicat- In this posithe lattersufiiciently to provide between them a vertical groove or channel 22 inwhich moves one edge of the screen. Fitted within the ends of the guidesare short upper and lower bearing blocks 23 having transverse openingsthrough which pass screws 17 or other securing devices, which thusfirmly support the blocks while also holding the guide to the windowframe, and the bear mg blocks reciprocally impart necessary strength tothe guide to resist all strains incident to tightening of the screws 17.f

An important feature of construction consists in inclosing the screenedge clamps within the screen guides *to assure a more neat and pleasingfinish to the guides and the clamps and to the whole screen structure,and also to avoid unsightly and not easily removed dust accumulations,than prevails when the clamps are arranged outside of the guides andmore or less in full view. In this constructive feature the screenclamps inclosed in the guides may have any desired form and mode ofoperation, but it is preferred to form the clamps of a rod extending forpractically the full length of the guides. The clamping rod, indicatedby 24, has at its opposite ends journals 25 fitted in recesses in theopposed lower and upper faces of the respective upper and lower blocks23, preferably nearer the outer ends of theblocks and in such relativepositions as to cause the rod, when turned from the inoperativeposition, shown in Fig. 5, to that shown in Fig. 6, to bind throughoutits entire length upon the inner surface of the wall 15, near its stronglaterally curved edge, whereby the clamp rod 24 and both the inside andoutside walls 14 and 15 of the guide coact to mutually brace each otherwhile the edge of the screen 1 is clamped by the rod against the outerflange 14. A

further improvement consists in forming the screen clamping rod in amanner assuring its action gradually lengthwise upon the screen edge.This is conveniently accomplished by making the rod of a flat bar,

with rounded edges and imparting thereto a lengthwise twist, or apartial turn from end-to end, as shown in Figs. 2, 5 and 6, which causesthe rod when rotated to exert its clamping action gradually upon thescreen edge from one end portion of the screen to the other, thus makingthe manual operation of the screen clamps easier and more certain andbringing less strain upon the screen material than occurs when thescreen edge is clamped simultaneously along its whole length. Forturning the clamp rod 24, a drop handle 26 is provided having an endtongue 27, Inovably fitting within a vertical groove in the outer end ofa horizontal stud 28, fixed in the clamping rod 24,

and coupled to the stud by a pivot pin 35.

Whenassembling the parts the clamp rod 24 with its fixed stud 28 isfirst slipped endwise into the hollow guide, and the rod adjusted .toproject its stud 28 outwardly through a slot 29 in the wall 15, as shown-26 may now be coupled to the stud 28 by ;the pin, 35, and will normallydepend 1n front of the screen guide.

When the screen 1 is drawn downwardly in its-two guide channels, thehandles 26 will be raised horizontally and will then be turned aboutone-quarter around toward the screen, as shown in Figs. 1 and 6, therebycausing the rods 24 to securely clamp the opposite edges of the screenagainst the guide flanges 14. The handles being then released drop to avertical position at the inner edges of the guides. Whether the screen 1be drawn downwardly and clamped, or unclamped and rolled upon the roller2, the drop handles 26 are practically the only visible portion of thescreen clamping mechanism and they present a pleasing appearance inkeeping with the appearance of the clamp concealing guides,withoutmarring the architectural symmetry of the window design ortrimmings. 1

It will also be noticed that'by concealing the screen edge clamps 24within the guides, the nature of the screen clamping-mechanism is notreadily apparent because of the lateral projection of the guide flange14 beyond the inside wall 15 so that an intruder would find it diflicultto pry the clamps loose from the outside of the window without destroy:ing the screen, hence this invention permits keeping the window sashesopen for ventilation while providing a substantial measure of protectionagainst the unlawful entrance of an intruder. As an additional lockingdevice the bottom rail 11 of the screen carries on each of its endblocks 12 a latch 30 pivotedto a lug 31, and having ahook end 39 adaptedto automatically lock into the recess 32, made at the lower end of theedge of each guide flange 14, as shown in Fig. 1 of the drawings. Thelatches 30 swing outwardly at their lower ends and about at right anglesto the face of the screen, and their inner plate portions preferablyrange about parallel with the screen and may be used as convenientfinger grips in manipulating the screen.

The rotation of the engaging. edges of the clamping bars or rods 24 1sin a direction outwardly toward the screen to move its edges intocontact with the guide flanges 14 and also laterally thereof, thustending to draw the edges of the screen outwardly in opposite directionsto stretch it with suflicient tension to cause'it' to lie flat over theentire opening and prevent it from bulging. In this position one edge ofeach clamping rod is in engagement with the curved edge of,

the inner flange 15 which serves as a bear-' ing or brace to stiffen therod throughout its length and resist any tendency of the rod to buckleif pressure is applied 'transversely of the screen.
